Below, the vertical frame fixing device 6 for fixing the second vertical frame 25 to the building structure 11 will be described in detail, and a description of the vertical frame fixing device 6 for fixing the first vertical frame 24 to the building structure 11 will be omitted.

As shown in FIG. 7, the vertical frame fixing device 6 has a vertical frame fixing member 61 fixed to the second vertical frame 25, and a frame fixing member 62 fixed to the building frame 11. The vertical frame fixing member 61 and the frame fixing member 62 are capable of relative displacement in a first direction, and relative displacement in a second direction perpendicular to the first direction is constrained. The vertical frame fixing device 6 is installed so that the vertical frame fixing member 61 and the frame fixing member 62 are capable of relative displacement in the width direction, and relative displacement in the indoor/outdoor direction is constrained. The following explanation assumes that the vertical frame fixing device 6 is installed in the above-mentioned position.

The vertical frame fixing member 61 and the frame fixing member 62 are formed, for example, from metal. The vertical frame fixing member 61 is bolted to the vertical frame outer panel portion 241. The frame fixing member 62 is bolted to an angle bar 18 fixed to the building frame 11. The angle bar 18 is provided near the side edge of the frame opening 12 on the interior 13 side of the exterior wall 111. The angle bar 18 is a long member with an L-shaped cross section, and is arranged so that it extends vertically.

The vertical frame fixing member 61 has a vertical frame fixing piece 63 and a protruding piece 64. The vertical frame fixing piece 63 is arranged along the other widthwise surface of the vertical frame outer plate portion 241 (the surface facing the edge of the frame opening 12). The protruding piece 64 protrudes from the vertical frame fixing piece 63 to the other widthwise side. The vertical frame fixing piece 63 is formed in a flat plate shape and is bolted to the other widthwise surface of the vertical frame outer plate portion 241 with the plate surface facing the widthwise direction.

The end of the vertical frame fixing member 61 on the indoor 13 side comes into contact with the portion of the vertical frame indoor side plate 244 of the second vertical frame 25 that protrudes to the other side in the width direction beyond the vertical frame outer plate 241 from the outdoor 14 side. The sealant 81 and the insulating material 82 provided between the vertical frame outer plate 241 and the side edge of the frame opening 12 are positioned on the outdoor 14 side of the vertical frame fixing portion.

The frame fixing member 62 has a frame fixing piece 65, an exterior protruding piece 66, and an interior protruding piece 67. The frame fixing piece 65 is formed in a flat plate shape, and is bolted to the angle material 18 from one side in the width direction with the plate surface facing the width direction. The exterior protruding piece 66 is formed in a flat plate shape, and protrudes from the edge of the frame fixing piece 65 on the exterior 14 side to the other side in the width direction with the plate surface facing the indoor/outdoor direction. The interior protruding piece 67 is formed in a flat plate shape, and protrudes from the edge of the frame fixing piece 65 on the interior 13 side to the other side in the width direction with the plate surface facing the indoor/outdoor direction. The exterior protruding piece 66 and the interior protruding piece 67 are arranged with a gap between them in the indoor/outdoor direction.

The frame fixing member 62 is surrounded by the frame fixing piece 65, the exterior protruding piece 66, and the interior protruding piece 67, and has a frame fixing member groove 68 that opens on one side in the width direction. The frame fixing member groove 68 extends in the vertical direction. The frame fixing member 62 has a U-shaped shape when viewed from the vertical direction. The distance between the exterior protruding piece 66 and the interior protruding piece 67 (the width of the frame fixing member groove 68) is formed to be the same as or slightly larger than the indoor/outdoor dimension of the tip portion 641 of the protruding piece 64 of the vertical frame fixing member 61. The protruding piece 64 is inserted into the frame fixing member groove 68 from one side in the width direction. A distance is provided between the tip portion 641 of the protruding piece 64 and the bottom of the frame fixing member groove 68 (the surface on one side in the width direction of the frame fixing piece 65). This distance is, for example, 5 mm. A gap is provided between the tip of the exterior protruding piece 66 and the tip of the interior protruding piece 67 and the vertical frame fixing piece 63.

The vertical frame fixing member 61, which connects the second vertical frame 25 to the building structure 11, and the structure fixing member 62 can be displaced relative to each other in the width direction within the range of the distance between the tip of the protruding piece 64 of the vertical frame fixing member 61 and the bottom of the structure fixing member groove 68 of the structure fixing member 62. The relative displacement between the vertical frame fixing member 61 and the structure fixing member 62 in the indoor/outdoor direction is restricted.

In the fitting 1 according to the above embodiment, the upper frame exterior plate portion 225 of the upper frame 22 is provided as a drainage portion that guides rainwater that hits the upper frame 22 from the outside room 14 downward, so rainwater can be prevented from entering the upper rail groove portion 716 of the upper frame 71. In the fitting according to the above embodiment, if rainwater runs down the top surface of the upper frame upper plate portion 711 and enters the room 13 side, the inclined plate portion 751 becomes a water return portion, and the rainwater can be prevented from entering the room 13 side beyond the upper frame 71.

In the above embodiment of the fitting 1, an airtight material 84 (first gasket) is provided between the upper frame 22 and the indoor surface of the indoor facing plate portion 752, which is connected to the indoor side of the inclined plate portion 751 (water return portion). This prevents rainwater from entering the space between the upper frame 22 and the upper frame 71 and entering the indoor side of the single sliding screen 4 from above the upper frame 71.

In the fitting 1 according to the above embodiment, an airtight material 83 (second packing) is provided between the exterior surface of the upper rail 229 of the upper frame 22 and the side surface (first groove plate portion 754) of the upper rail groove portion 716 of the upper frame 71. This makes it possible to prevent rainwater from entering the upper rail groove portion 716 even if the rainwater enters between the upper frame 22 and the upper frame 71.

In the above embodiment of the building fixture 1, the airtight material 84 (first gasket) and the airtight material 83 (second gasket) are arranged in positions facing each other in the indoor/outdoor direction. This allows the watertightness and airtightness between the upper frame 22 and the upper frame 71 to be maintained from both the outdoor side 14 and the indoor side 13, improving the watertightness and airtightness.

This disclosure is not limited to the above embodiment, and can be modified as appropriate without departing from the spirit of the disclosure. For example, in the above embodiment, an airtight material 84 (first gasket) is provided between the indoor surface of the indoor side facing plate portion 752, which is connected to the indoor side of the inclined plate portion 751 (water return portion), and the upper frame 22. An airtight material does not have to be provided between the indoor surface of the indoor side facing plate portion 752 and the upper frame 22.

In the fitting 1 according to the above embodiment, an airtight material 83 (second packing) is provided between the exterior surface of the upper rail 229 of the upper frame 22 and the side surface (first groove plate portion 754) of the upper rail groove portion 716 of the upper frame 71. An airtight material does not have to be provided between the side surface (first groove plate portion 754) of the upper rail groove portion 716 of the upper frame 71.

In the above embodiment of the building fixture 1, the airtight material 84 (first gasket) and the airtight material 83 (second gasket) are arranged in positions that face each other in the indoor/outdoor direction. The positions of the airtight material 84 (first gasket) and the airtight material 83 (second gasket) may be set as appropriate.
